Title: Minimum flow control device for feed water pump
Inventor: TSUJI HIROSHI
IPC: F22D5/32
Filed: 1989-03-20
Abstract: PURPOSE:To perform a safe operation without damaging a well-balancedness and a controllability of a turbine driven feedwater pump by a method wherein even if a fast M/T changing-over time occurs, a minimum flow valve is released to open until the number of revolution of a feedwater pump driven turbine reaches more than a predetermined value. CONSTITUTION:A feedwater pump driven turbine 10a is provided with a sensor 20 for sensing the number of revolution. A signal for the number of revolution of a feedwater pump driven turbine 10a detected is also inputted to a minimum flow valve control device 17. Then, as the minimum flow valve for a turbine driven feedwater pump is opened, a flow rate of condensate flowing in the turbine driven water supply ing pump is increased, and a suction pressure of the turbine driven feedwater pump is decreased. In this way, even if a suction flow rate of the turbine driven feedwater pump is more than an allowable value after changing-over of M/T, the minimum flow valve for the turbine driven feedwater pump is continued to open until the number of revolution of the feedwater pump driven turbine has a sufficient number of revolu tion in respect to a dangerous number of revolution and then the operation of the feedwater pump driven turbine is not carried out in a range near the dangerous number of revolution.

Title: Induction heater for roll
Inventor: ZEFUREE HENRII PARUKOUSUKII
IPC: H05B6/36
Filed: 1986-03-27
Abstract: Inductors for heating rolls especially of the type used in rolling mills for sheet materials such as paper, textiles, plastics and the like, are configured to enhance and concentrate eddy currents in areas along the length of the roll to selectively heat the roll as desired and control moisture and caliper properties of the sheet. The inductors have cores with a center leg around which the exciting coil is wound and an outer leg surrounding the coil and connected at one.end to the inner leg. These inductors or electromagnet are mounted immediately adjacent a roll of magnetic flux conducting material, such as iron or steel, to heatthe roll surface as desired across the length of the roll as it is rotated through the concentrated electromagnetic field generated by the inductor. The magnetic field or flux is concentrated in an annular zone and passes between the nested inner and outer legs of the core through the roll without travelling through a wide air gap and the desired roll temperatures are achieved with minimum current input to the coil. The air gap may be varied in the cross machine direction and the excitation of the inductors may be varied to induce or compensate for temperature variations across the roll.

Abstract: PURPOSE:To simplify and miniaturize the title apparatus and to effectively enhance a washing degree by providing a washing treatment part rotating an object to be washed and capable of performing operation for moving a washing body from the center of rotation in a centrifugal direction and a drying treatment part adjacent to said washing treatment part through a partition. CONSTITUTION:At the time of the washing work of an object to be washed, the object to be washed is rotated by mechanism 17 for the object to be washed and washing nozzles 18a, 18b, 18c, 18d are operated during this rotary operation by a washing body driving mechanisms 20a, 20b, 20c, 20d so as to be moved from the center-of- rotation position of the object to be washed in a centrifugal direction. By moving the object to be washed from the center-of-rotation position thereof in the centrifugal direction with the movement of this nozzle group to successively wash the same, two or more stages of washing processes in a single washing treatment part 14 are made possible to appropriately change over to simplify and miniaturize the apparatus as a whole. Further, when washing is completed, a partition plate 25 is opened and closed to send the object to be washed to a drying treatment part 15 and the object to be washed is subjected to drying treatment. Therefore, a residual washing solution is not dripped on the object to be washed because of the drying in the washing treatment part and a washing degree can be enhanced effectively.
